'The body's metabolism is reflected in the compounds present in the exhaled breath. On the basis of minuscule molecules, which are chemically altered or…
Soft materials that are periodic on the submicrometer length scale act as both hypersonic phononic and visible light photonic crystals. This means: they…
Regular physical activity is a highly effective means of lowering the risk of developing diabetes. However, patients respond in very different ways. In about…
During laser beam welding the focus position of the laser beam should be on the workpiece surface. With the present invention, this focus position can be detected in relation to the workpiece. Thus, the process can be set up quickly, but also the focus shift could be compensated. Also, this method can prepare the basis for calibrating scanner optics.
A huge earthquake may be building beneath Bangladesh, the most densely populated nation on earth. Scientists say they have new evidence of increasing strain…
Ever play with a magnifying lens as a kid? Imagine a lens as big as the Earth. Now focus sunlight down to a pencil tip. That still wouldn't be good enough for…
For only the second time in a year, a NASA camera aboard the Deep Space Climate Observatory (DSCOVR) satellite captured a view of the moon as it moved in front…
Two Northwestern University neuroscientists have identified the neurochemical signal likely missing in Parkinson's disease by being the first to discover two…
Carbon nanotubes can be produced with a variety of shapes and properties and are therefore of much interest for widespread applications in fields as diverse as…
The beta cells of the pancreas produce the metabolic hormone insulin when blood glucose levels rise, in order to keep glucose levels in equilibrium. If the…
Graphene, a two-dimensional wonder-material composed of a single layer of carbon atoms linked in a hexagonal chicken-wire pattern, has attracted intense…
The pigment that gives spinach and other plants their verdant color may improve doctors' ability to examine the human gastrointestinal tract.
Stomach MRI images combined with functional fMRI of the brain activity have provided scientists new insight into how the brain listens to the stomach during…
An international team has made use of the power of the HAWK-I infrared instrument on ESO's Very Large Telescope (VLT) to produce the deepest and most…
In most materials, the nuclear spins of neighboring atoms have only a very weak effect on one another, as the tiny nuclei are located deep within the atoms….
Most systems in nature are inherently nonlinear, meaning that their response to any external excitation is not proportional to the strength of the applied…
